'ings includes a base member or frame 1,.

comprising an elongated middle portion, near the ends and on oppositesides of which, are alined lateral extensions 2. In other words, thepiece is substantially H- shaped. The middle portion and lateralextensions are of channel section, the flanges being disposeddownwardly; At the ends of the lateral extensions 2 are ears 3 which areperforated to receive securing bolts 4 by which the basemember issecured to a supporting stand or table, which latter,.of it self,forms-no particular part of the present so i invention, and-may be ofany suitable construction. As shown in the drawings, the

' stand comprises parallel horizontal channel members '5 which aremounted on uprights'fi.

The uprights may also be made of channel or angle section and suitablybraced with respect to each-other and to the horizontal members.

The base member 1 is provided on top and bottom with alined bosses 7 and8, respectively, with. vertical bores therethrough to receivereciprocatory bars 9, there being preferably four of these-arranged inrectangular relation. Secured on the upper ends of the bars '9'. is askeleton frame 10 of substantially H-shap'e, the same being suitablystiffened by ribs 11. Interposed on the bars 9, between the bosses 7 ofthe base member and the frame 10, are loose sleeves 12 of rubber orotherv suitable cushioning material on which said frame 10 rests in itslowered position as will presently appear. The bars 9 arefurtherprovided with fixedcollars 13 below the base member 1, said collarsbeing arranged so as torest on a vertically-movable actuator plate 11 tosupport the frame 10 in raised position, said actuator plate havingopenings extending through downwardly-disposed bosses 15- thereon. andthrough which the bars 9 slide. Extending .up through a slot 16 in saidactuator plate and pivotally'secu'red between two cars 17 on the topthereof is a link 18. The lower end this'link is placed between andpivota'lly secured to the end portions ofa-pair of lever arms'19,.thelatter being pivotally mounted at their opposite ends betw'een two ofthe uprights 6 at the front of the supporting stand, as at 20. The leverarms are pivotally connected by a link 21 with a treadle lever 22 whichis pivotally mounted betweentwo rear uprights 6 of the supporting stand.

through it, the parts connected thereto, are

yieldably held in normal raised position by a spring 23 which is securedat one end to the treadle lever and at-its opposite end to the rearhorizontal member 5 ofthe supporting stand.

Detachably secured on the frame 10 is a plate or table member 24 onwhich the article to be wrapped is supported. As shown,

this plate is provided with downwardlyextending marginal flanges 25which serve to strengthen it, while inwardly from the endmost flangesare transversely-disposed flanges 26 which are located so asto fitsnugly against the inner sides of correspondingly-arranged lugs 27projecting upward from the frame 10, there being lugs 28 providedadjoining theflanges 26 on the plate toengage the ends of said rib. Bythis arrangement the lugs 28 form with the flanges 26 pockets into whichthe lugs 27 fit so as to prevent longitudinal and lateral displacementof the plate. The plate is pro- 30 vided at its middle with a boss 29through which extends a countersunk hole in line" upturned portions 32of the angle pieces are rounded off somewhat pointedly, as best shown inFigs. 2 and 6, for a purpose which will later be set forth. f

Mounted on the cross arms 2 of the base member 1, on opposite sides ofthe :vertically movable article-supporting table just described, arevertically-disposed side plates 35 whose inner faces are plain, but onwhose outer faces are provided stiffening ribs 36 which merge at theirlower ends with horizontal base flanges 37. The base flanges areerforated to receive securing bolts 38 which are carried through slots39 provided therefor in the cross arms 2 of the base frame 1. The boltsare securedbynuts ,40, but with 60 sufficient looseness to allow theside plates to be moved toward and away from each other. To effect theadjustment of the side plates and to hold;them in.a.dj usted position, ascrew 41, having right and left hand threaded pontionsz'42, 43, isarranged so as The treadle lever, and

me eee to engage counterpart threaded portions44, 45, respectively, onsaid side plates. The screw is held from en'dwise movement by having acollar 46 thereon inserted between a pairof lugs .47 on the middleportion of 7- the base member 1, said lugs 47 being slotted to provide abearing seat for the screw. A handwheel or other suitable handle 48 maybe"provided at either or both ends of the screw, as desired. Obviously,by rotating 5 the screw the side plates will be moved toward or awayfrom each other, depending upon the direction of rotation.

At the tops of the side plates are. outwardly and upwardlyinclinedextensions go or brackets 49 on which are secured oppositely-disposedplates 50, 51, said last-mentioned plates extending on opposite sides ofsaid side plates. The lower edge portions of the plates 50,51, arebeveled in the region 5 of the side plates 35, as at 52, so as to beflush with the vertical-inner faces of said side plates. The twoinclined plates 50, 51, form with, the vertically-movablearticlesupporting plate 24 which, in normal raised position, occupies aposition slightly below the lower edge portions of said plates 50, 51, atrough-like affair in which'the sheet of wrapping paper is initiallyplaced. This arrangement embodies one of the salient features of theinvention, namely, the provision of means for first giving tothe sheetof wrapping paper a shape which will facilitate the formation of thesuccessive folds of the wrapper with regularity and uniformity.

The wrapper blank or sheet, indicated generally by the letter A, isplaced in the trough so as to be disposed equally both sidewise andendwise with respect to the middle of the article-supporting plate 24,the wrapper beinglaid loosely at first and 1 resting at its middle onthe, upturned portions 32 'of-the angle pieces 32. The article to bewrappedin the drawings, a repre- 11G sentation of a loaf of bread upsidedownis placed on the supporting plate 24 thereby depressing the'wrapperbetween the members 32 drawing. the wrapper snugly to the loaf, andcausing the middle of the end portions to pucker upwardly, as at a withoppositely puckered portions 6 on either side thereof at the corners.With the wrapper in this shape, the plate 24 is lowered, causing thewrapper to be drawn up close about the lower portion of the loaftransversely thereof. During the downward movement of the plate 24, theupstanding portions 32 of the angle pieces 32 travel in close proximityto end-plates 53 which engage the puckered portions a of the wrapper soas to further fold. the same up closer to the ends of the loaf. The topedges of these plates 53 are rounded off or crowned, as at 53 to avoidtearing the wrapper. Said its lowermost position, the loafv will havebeen moved down entirely below the lower edge portions of the plates 50,51, so that'the side portions .of the wrapper assume a verticalposition, while the endpor'tions which were initially puckered as at aand b are folded respectively close to the end of the loaf and to theadjacent upstanding side end portions 0 of the wrapper as shown in Figs.9 and 10. After the folds have reached this stage the side end portions0 are folded in against-the plates 53 in a manner and by means now to bedescribed.

Carried'by the side plates 35 are side end folders 54:. These comprisewings or plates having angularly-extendinglugs 55 which are securedtightly on vertical shafts 56. The shafts are journaled in extensions57, 58, of bracket members 59 which are secured on the outer faces ofthe side plates 35. These bracket j members have horizontal slots 60through which retaining screws 6], are inserted into'the sideplatessothat the wings or folders 54 can be adjusted to suit theadjustment of the angle pieces 32 and plates 53.

To facilitatethis adjustment the retaining.

screws 61 are fitted with just suiiicient looseness to allow the bracketmembers 59 to move easily, and the pair of oppositely-disposed bracketmembers on'each side plate are pro-' vided with lugs 62 having righta-ndleft- .hand screw-threaded horizontal holes to receive thecorrespondingly-threaded end portions of a screw 63. This screw isjournaled through openings provided therefor in the vertical ribs 36 ofthe side plate. and it has a collar 64 fixed thereon and fitted betweenbosses 65 provided on the inner'faces of said the screw to'efi'ect theadjustment of the I ribs 36 so as to prevent endwise movement of thescrew, said collar being provided with a milled or knurled wheel 66 bywhich the screw may be easily manipulated By this arrangement it is onlynecessary to rotate members 59 inwardly and outwardly, the screw holdingthem in position after the desired adjustment is attained.

The lower'extensions 58 of the members- 59 whose end portions 'areturned downward as at 67 have bearing collars 58 rotatably fittedtherein. Said bearing collars are pro vided .a'ttheir ends with thrustshoulders and have square axial openings through which extend the endportions of a crank shaft 69 which is also of square section by whicharrangement the shaft is afforded a rotatable bearing and at the sametime ad ustment of the bearingendwise of the shaft is permitted, Bevelgears 70, also having square openings therethrough, are arranged on thecrank shaft 69 so as, to rotate therewith, but being slidable lengthwisethereof acent to the, bearing collars 68, said bevelgearsmeshingfwithvsimilar gears 71 on the lower ends of the foldershafts 56, the arrangement of' the coiiperating gears being such thatthey are maintained in proper relation at all times without interferingwith the adjustments. above set forth; 7

The two crank shafts, there being one on either side of the machine,have crank portions 72 in which are pivotally secured the upper endportions of actuator rods -7 3. These rods hang loosely from said cranks72' through slottedor bifurcated lat-- eral extensions 74 of theactuator plate 14 and they are provided with stop-collars orenlargements 75, 76, respectively, above and below the actuator plate,said collars being relatively arranged so that the plate engages themalternately during its reciprocation,

and whereby the crank shafts are oscillated. The slotted or bifurcatedextensions 74 are of sufficient length to permit the side plates 35 tobe shifted with respect to each other without interfering with" thecoiip'erative relation ofthe rods 73 with" the actuator plate.

As shown in the drawings, provision is made for the travel of the cranks72 approximately through an angle ofv ninety degrees', which distance isdistributed equally above and below a horizontal line through the axes:of the shafts 69. Retractile springs 77 are connected at one end to.loops 78 which are swiveled on the pivots from which the actuator rods73 are suspended. The opposite ends of the springs are fastened to studs79 projecting from theribs 36 on the outside of the side plates 35 insame plane as the axes of the crank shaft,

said springs being carried through vertically elongated openings 80'provided therefor in the side plates. By this. arrangement the springs77 complete the actuation of the cranks after the latter have been movedto either side of dead center bythe engagement' of the actuator platewith the collars 75 or 76 as thecase may be. In folding the side end orcorner portions of the wrapper inward, the pair of folders or wingsoperating'on one side plate are madeto move in advance of those on theother side plate. That is, the wings on one side fold the cornerportions 0 on the corresponding side ofthe wrapper in against the plates53 and the other wings fold the opposite corner portions 0 ofthe-wrapperin upon the first-mentionedwings. The wrapper folds have thenreached the stage as illustrated in Fig. 11, in which form the wrapperextends all about and above the sides 'of the article. The folded overside end or corner portions 0 are next, folded in upon the top of thearticle as at cl, causing the adjacent portions of the sides of thewrapper to fold triangularly against the inner face thereof as at eleaving two upstanding flaps f. The mechanismfor accomplishing this willnow be described frame 1 are end folders which may be indi catedgenerally by the numeral 82. These folders, as shown, each comprise abellcrank having a flanged arm 83 and a bifurcated arm 84, saidbell-crank be- .ing pivoted, as at 85, on a stud which is mounted on theside webs 86 of said angle bracket 81. Depending from between thebifurcated arm of the bell-crank 84c to which it is pivotally secured,is an actuator rod 87 which extends through a Slotted or bifurcatedextension 88 at the end of the actuator plate 14. This rod has a.

stop collar or enlargement 89 thereon beneath said actuator plate so asto be engaged by the latter as'the same moves downward andthereby-actuate the bell-cran'kas will -presently be described.

Adjustably mounted on the arm 83 of the bell-crank, as by having a slot90 therein" through which securing bolts 91 project 95, and anotherspring 98 is interposed between the opposite side of the member 95 and anut 99 at the end of the bolt. The springs 97, 98, serve to center themember 95 and permit it to yield in opposite directions to giveflexibility to the end .folder mechanism in order to compensate forirregularities in the contours of the top portions of the articleswrapped upon the machine.

Secured across the outer end'portions of,

the forks 100 of the member 95 is a thin plate 101 having an offsetouter portion 102 whose edge is rounded or'crowned after the manner ofthe initial folder plates 53 so as not to tear the wrapper. {This plate101 is arranged so as to press against the outer lap of the infoldedside portions 0 of the wrapper at the stage shown in Fig. 11 so as toturn said portions inwardly over the edge of the loaf or article beingwrapped as the end folder moves into the position shown in Fig. 3.Tnthis operation the fold is partially effected. lInother words, the

Hingedly mounted on angle brackets 81 at the opposite end portions ofthe base greases portions of the wrapper engaged by the plate 101 arepressed inward at such an angle approximating a horizontal that the foldmay be readily completed by a wing plate 103 which is hingedly mountedon the member 95 so as to engage the portion of the wrapper thusinfolded at this stage with an inward and downward sweep Whereby thewrapper is drawn endwise as well as pressed down against the top side ofthe article.

'As shown, the wing plate is bent or curved slightly so that its edge104 may move to a plane below that occupied by the offset portion 102 ofthe plate 101. so as to press the wrapper close upon the article andpermitting the portion 102 to move over the edge portion of the articlewith suflicient clearance to avoid shearing or tearing the wrapper. Thewing plate is carried by a mem-v ber 105 which is provided withangularlydisposed legs 106 straddling the members 95 and 92, said legportions being pivoted, as at 107, on lugs 108 extending upwardly fromthe forks 100 of the member 95 close to the body portion of said member.105. The member 105 has a lug 109 projecting there from and to which issecured one end of a spring 110 whose opposite end is attached to a lug111 projecting from the web of the member 95, said spring being providedto complete actuation of the carrier of the wing plate with a' quicksnapping action when it has been moved ineither direction past a deadcentral position with respect to the axis of the pivot 107 and line ofpull of the spring.

Normally, when the end folders are in the down position as shown in Fig.1, and when traveling from that position to fold the wrapper, the wingplate 103 sets away from the plate 101, while the legs 106, whose endportions have angular extensions or feet 112, projectforwardly to aposition so that they are brought against the side end or corner folderwings 54: just about the time the edge of the portion 102 of the plate101 engages the wrapper. .The arrangement of the legs 106-is such that,being arrested by coming in contact with said folder wings 5d, thecarrier 10 5.for the top folder wing plate 103 is caused to move withrespect to the member 95 on which it is mounted, said member 105 beingmoved past dead center just after the plate 101 has been brought to restwith its portidn 102 overhanging the end of the article being wrapped.The spring 110then snaps the wing plate 103 down against the top of thearticle and completes the folds of the wrapper to the stage shownin Fig.12, in which stage the several folds are held snugly in place'by theseveral springs 77, 98, and 110 which respectively act upon the folderdevices with whichfthey are associated. Asthe end folders 82 move backto 1.

The pressure on the treadle lever is thenrelieved, permitting the spring23 to raise the actuator plate through the medium of the links andlevers connecting the latter;

with said treadle lever.' After the support- I ing plate or table 24 hasbeen restored to its normal elevated position the wrapped article isremoved therefrom and the wrapper may then be sealed in any desirablemanner.

As the supporting plate 24 rises the several folder devices arewithdrawn from -en,- .gagement with the wrapper, the 'top end folders 82dropping by assisted at the start by t e article pressingavity, andbeing upwardly against the wing plate 103 and also by springs 114carried by said'end folders and engaging the angIe-brackets-Sl,

while the side-end or corner folders 54 are swung back tonormalposition, after the article has been lifted high enough to disen gagethe flaps 0 from said folders 54, by the engagement of the actuatorplate 14 with the collars 75 on the rods 73 which in turn ing plate '24disengages the wrapper from i the initial folder plates 53, after whichthe wrapped article is free to be removed from f the supporting plate.

To adjust the end folders 82 to correspond with the adjustments of theother folders as hereinbefore set forth, the angle brackets 81 areprovided with blocks or lugs 115 which project downwardly through slots116 in the base frame 1 and arerespectively provided with right and lefthand screwthreaded' openings to receive counter art threaded portions117 of a screw 118. aid screw 118 has a collar 119 at the middle thereofengaged between two lugs 120 which are recessed as at 121 to provideseats for the screw. The screw is provided at either end with a handwheel 122.

To provide for the interchangev of the initial end folder plates .53 tosuit adjust.

ments of the machine for Wrapping loaves or articles of differentwidths, said plates are ferent widths, but mounted on standardized"clips and provided in the equipment of the machine, so as to be readilyinterchanged when it becomes necessary to adjustthe side plates 35toward or away from each other.
